If (2Z,4Z)-hexa-2,4-diene were able to undergo a Diels–Alder reaction with methyl propenoate, what would be the products? (Hint: There are four products comprised of two pairs of enantiomers. One enantiomer pair would predominate.) In reality, this Diels–Alder reaction is impractical because the s-cis conformation of the diene required for the reaction is of high energy due to steric hindrance between the methyl groups.

The boiling point of liquids is very high what does it indicate
